I have been watching the owner's thread (LINK) waiting for some info on the Service Menu, but it's been pretty slow coming. Since I am having a color issue I decided to dive right in. Here are my findings specifically from a WD-73737. Please correct or add more info and I will update this post.

I would really like to know what these are.

Service Menu Notes

Menu 2 4 5 7 to enter service menu

Live signal remains onscreen, press Play to “enable” test patterns. Use FF and RW to cycle through patterns. Press Play again to return to live signal. Patterns can be changed on any Sub Screen which allows you to select the best pattern for the adjustment you are making, except Geometry screens.

8.CCA
High/Low Temp settings for Brilliant/Bright/Natural 1=On 0=Off
When Off, the maximum is set for each color (128) and the High/Low Temp setting has no affect in the Brilliant/Bright/Natural presets.High and Low Temp settings can be set individually for each Temp and for each preset.
CCA is also applied when you are using the ADV menu. However, since there is no High/Low setting in ADV, you only have the Low CCA setting.
The individual color settings below are only available when CCA is set to 1 (On). You will see L or H depending on your Temp setting.

Perimeter
Caution: Pressing 1 will reset your adjustments for all geometry screens!
- The start point is in the upper left corner and may not be onscreen, but it’s there.
- Adjust the point (if needed) with the arrow keys. The lines won’t move, just the point.
- Top and bottom points move Up and Down only. Side points move Left and Right.
- Corner points move in a four directions.
- Press FF to move to the next point in a clockwise direction. RW moves you counter-clockwise.
- You must advance to the next point after making a change.
- Press Enter to “set” your adjustments.
Here is the process I used for the perimeter.
Move all adjustment points as far to the center as possible.
Use the Horizontal/Vertical adjustments to center it as best you can.
Now adjust the top line outward to the very edge of the screen. Keep it straight using the bezel as a guide.
Continue with the same process for the remaining 3 sides.
Make any final centering adjustments.
Move on to the interior lines.

Interior Lines- From the Perimeter screen press Page Down.
- The 4:3 lines are highlighted in blue.
- FF and RW make incremental adjustments, just pick the best one.

- From the 4:3 screen press Page Down.
- The top Letterbox line is highlighted in red.
- FF and RW make incremental adjustments, just pick the best one.

- From the top LB screen press Page Down.
- The bottom Letterbox line is highlighted in red.
- FF and RW make incremental adjustments, just pick the best one.

with option: 61.DBK - It doesn't really matter what you set it to, 0 or 1 - it reverts back to the default setting, picture-wise.

I believe this is the Dark Detailer option from the 837 series, but it's usage is disabled on the 737, since no matter what you set it to - when you exit the menu it defaults back to factory, and the picture is not as bright/crisp as when you change it to "1" after first changing it to "0" in the SM.

also - my other numbers quite a bit different.

My factory defaults are:

GRWH - is set to 127

GGWH - is set to 106

GBWH - is set to 122

So obviously, Mits does some factory tuning on these sets before they ship.

Also - the CCA setting, when set at "1" disables the otehr color temp setttings. GRWH, GGWH, and GBWH are no longer configuarable with this option set to "1".

I found some info on the CCA item. It came from a Samsung post but I assume it still applies. Appears to be an "auto color" type of function. Still waiting on some confirmation tho.

"CCA is Samsung's color coordinate adjustment system, which automatically corrects primary and secondary colors to system specifications, and therefore must be temporarily disabled before performing calibration of color and tint."

Hmmm.... This makes me wonder if there is a possibility of flashing the 737 to 837 firmware, that way you can get the dark detailer function in a 737

I have a WD-60737, and am unable to get the geometry right. When horizontal images/lines are displayed in the upper half of the screen, they bow down in the center (pincushion effect?). I also saw in one thread that one owner had checked/adjusted his overscan settings. I tried to adjust the screen geometry via the 16-points around the edge of the screen to no avail. Could my overscan settings be off, therby preventing proper adjustment of the 16-point adjustments? Any info/thoughts links to advice would be GREATLY appreciated. I'm feeling kinda sick right now because it was much better before I tried to tweak it to be even better. :-(

While you are in the Manual Geometry screen, press the Play button. This will bring up the 4:3 and 16:9 adjustments. Use FF/RW to select a setting, then press Play again to advance to the next one. Just try to pick lines that appear the straightest. It took me several tries.

The crazy thing is, I have gone to both the 4:3 and 16:9 adjustments, and the lines I selected WERE straight. I don't understand how I could still have images in the top half of the screen that are bowed down in the center.

Can you post a picture?

Also, don't save any manual geometry changes until you are certain you have things where you want them.

I was thinking, perhaps these aren't for gray scale adjustment. Most likely they set the contrast level for that color sort of like the general contras5t control but for each primary. or they could be gain controls for use with the 3 primary color point when adjusting color accuracy.

Many people have mentioned that they use such and such preset with High Color Temp or Low Color Temp, but when I tried those settings there was no perceivable difference. So I just quit trying to use Color Temp.

Then I was messing around with CCA again tonight and I happened to try the Color Temp setting again. To my surprise, it was now working. This made me curious so I started experimenting. I found that the CCA settings are in fact the High and Low temp settings. Here is what I added to the original post.

8.CCA
High/Low Temp settings for Brilliant/Bright/Natural 1=On 0=Off
When Off, the maximum is set for each color (128) and the High/Low Temp setting has no affect in the Brilliant/Bright/Natural presets.
High and Low Temp settings can be set individually for each Temp and for each preset.
CCA is also applied when you are using the ADV menu. However, since there is no High/Low setting in ADV, you only one CCA setting.
The individual color settings below are only available when CCA is set to 1 (On).

Ok, maybe not. I just tried to prove my theory by setting the same numbers for Low and High within the same preset. If I'm correct, when switching between Low and High the picture should stay the same, but it doesn't. It still pushes from cool to warm.

It does allow you to make changes to the Low and High temp settings for each preset, but there must also be an underlying setting that is preset to push your settings to warm or cool.

The crazy thing is, I have gone to both the 4:3 and 16:9 adjustments, and the lines I selected WERE straight. I don't understand how I could still have images in the top half of the screen that are bowed down in the center.

FIRST! : you should do your Horizontal/Vertical alignment (Overscan)
---After you have the best H/V position, PRESS 'ENTER' TO SAVE

SECOND! : Manual Geometry Alignment (16 points aligned flush with bezel)
---After going all the way around and you are back at the first alignment cursor,
PRESS 'ENTER TO SAVE'

So I believe that i was correct that these are grey scale corrections that adjust the upper and lower range at the same time. I have also found out the following

1) In Brilliant/Bright/and natural modes if you have the color temp set on Low then you will see GxWL in the service menu. If you have the color temp set to High, you will see GxWH. In ADV mode, you only have GxWL.

Once you set them, these setting stay the same no matter what activity you are in. for example, if you set GRWH, GGWH, GBWH while you are in Brilliant High temp. then the setting will automatically be updated in Bright High temp and normal High temp.

Also , if you set GRWL, GGWL, GBWL in ADV2 then these setting will also change in Brilliant, Bright, Norma Low temp and adv1

These setting are not input dependent. Meaning the stay the same no matter if you select Ant, DVD, HDMI1, or VCR

Does anyone have a C9, 737, or 837 with more options than this in the service menu?

I'm trying to set up a Mitsu 837 for my father and am having a bit of difficulty. The picture is much larger than the screen. I can find no setting which will enable me to fit the picture within the size of the screen.

Normally, I'd just contact our retailer, but they went out of business a month after we purchased the tv (good thing we bought a warranty from them ).

There are also geometry problems, but they are minor by comparison.

If this question isn't germane to this thread, please let me know, and I will post in the appropriate place.

I have an HTPC connected through hdmi. I am also seeing some bowing on the geometry. I have been able to correct most of it, but there is still some noticeable bowing towards the bottom of the screen (mainly if I have a 4:3 video playing, or the windows desktop)

I have aligned the 4:3 and the 16:9 as straight as possible (why can't we adjust them manually too?).

Is there a way to reset the input to have 100% straight lines? (the restore from backup has bowed lines)
